Control method of printing machine with heat dissipation assembly

Abstract

The invention discloses a control method of a printing machine with a heat dissipation assembly. A temperature sensor detects the temperature of the printing machine, a control element receives the temperature of the printing machine, when a received temperature value detected by the temperature sensor is less than a first threshold value, the control element controls a ventilation valve to be opened, when a cooling fan does not work, an adjusting plate completely seals cooling holes, a first control valve and a second control valve are closed, an air feeder is closed, the ventilation valve achieves air connection of the whole device, cooling is achieved through an outer shell and a channel material, after printing is finished, a controller controls the cooling fan to continue working forpreset time, the ventilation valve is closed, the cooling holes are completely closed, the first control valve is closed, the second control valve is opened, and when a pressure signal of the pressuresensor does not reduced any more, the cooling fan is closed and the second control valve is closed.

Description

technical field [0001] The invention relates to the technical field of printing machines, in particular to a control method of a printing machine with heat dissipation components. Background technique [0002] With the rapid development of social economy, printing machine refers to the machine for printing text and images. Modern printing machine is generally composed of plate loading, ink application, embossing, paper feeding (including folding) and other mechanisms. Its working principle is: first The text and images to be printed are made into a printing plate, installed on a printing machine, and then the ink is applied manually or by a printing machine to the place where the text and images are on the printing plate, and then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood, glass and ceramics), thereby reproducing the same print as the printing plate. [0003] However, the size of the heat dissipa...

Problems solved by technology

[0004] The purpose of the present invention is to provide a control method for a printing machine with a heat dissipation assembly, to solve the problem that the size of the heat dissipation hole of the heat dissipation assembly of the existing printing machine proposed in the background technology is fixed, and it is inconvenient to adjust. When the external environment causes internal overheating, it is not enough to ensure the normal heat dissipation of the printing machine, which will affect the normal operation of the printing machine, and it will be subject to problems such as dust and water intrusion
